Embodiment Construction

[0012] Such as figure 1 As shown, the present invention is made up of trip plate 4, electromagnet 3, top cap 2, button 1 etc. The button 1 is installed on the circuit breaker panel, the top cap 2 screwed on the button rod 11, the trip plate 4 that can drive the tripping half axis of the operating mechanism to rotate, and the electromagnet 3 installed in the mechanism.

[0013] The action process of the tripping electromagnet 3: the tripping electromagnet 3 is energized, its iron core sticks out and impacts the tripping plate 4, and pushes the tripping plate 4 to a certain position to complete the tripping of the circuit breaker.

[0014] Manual tripping action process: push the button 1 with your fingers, the top cap 2 connected to the button 1 pushes the iron core rod in the electromagnet 3, the iron core rod extends out, pushes the trip plate 4 to a certain position, and completes the tripping of the circuit breaker; When the torsion bar 11 is set to an eccentric structure...

Abstract

The invention relates to a tripping device of a high-voltage circuit-breaker. The tripping device of the high-voltage circuit-breaker comprises a button (1) installed on a panel, and an ejector cap (2) fixedly connected with a torsion bar (11) of the button (1), the ejector cap (2) is provided with an electromagnet (3) matched with the ejector cap (2), the ejector cap (2) corresponds to a core bar of the electromagnet (3), and the electromagnet (3) is provided with a tripping board (4) pushed by the electromagnet (3). As a series of technical measures are adopted, a guide board assembly and a push board are omitted, the structural design of the tripping board is simplified, and compared with a split type tripping device, the tripping device of the high-voltage circuit-breaker has the advantages of being compact in structure, small in occupied space and low in cost, thereby being small in switching-on bounce, reliable in tripping and the like.

Description

technical field [0001] The invention relates to a tripping device for a high-voltage circuit breaker, which has an electric and manual integrated structure. Background technique [0002] The operation of the high voltage circuit breaker is mainly completed by the operating mechanism. Its operation mainly consists of energy storage, closing, and opening. The device that operates the closing and opening is the tripping device. The existing tripping devices all have separate structures. as attached image 3 The structural composition includes a button installed on the panel of the circuit breaker, a guide plate assembly installed on the mechanism, a sliding push plate installed in the guide plate assembly, and a trip plate connected to the half shaft of the operating mechanism. An electromagnet installed inside the mechanism. The working process of the electromagnet: the electromagnet is energized, the iron core rushes out of the impact trip plate and pushes the trip plate ...
